fix network lib error: delete instead of delete[]

Please recompile network lib. Found by DrMemory.
I again hope this may have been the cause of all evil.
It has the potential to be I guess.

Full message by DrMemory included as I don't understand quite well
what happens in the lib, but it really seems a correct positive.
The pointer (memory address) as shown by the debugger is the same
for the new[] and delete[] statements, and this commit fixes the
DrMemory error message.

Revert the "custom standard types" stuff

Firstly, that templatish stuff was basically over my head, and more
severely, it somehow seems this introduced (or I want to test whether
it did...) memory problems, perhaps CString related.
Not much conflicts fortunately.

slight optimization: use iterator instead of .at(i)
